Imaging Phase Separated Domains in Conducting Polymer Blend Films With Near-Field Scanning Optical Microscopy
Jeeseong C. Hwang, Lori S. Goldner, Alamgir Karim, C L. Gettinger
We report on the use of near-field scanning optical microscopy to study phase-separation in polymer films of polmer films of poly(styrene) and poly (3-octylthiophene). Transmission and transmitted fluorescence near-field scanning optical microscope (NSOM) images were taken to directly visualize intermediate steps of phase separation in a regime where small domain sizes prevent investigation by conventional microscopy. The interpretation of near-field data on samples with large or varying film thickness or topography are also discussed and a method for analyzing topographically induced artifacts in a quantitative way is suggested.
